[U-Boot] [PATCH 1/3] samsung: board: support eMMC reset using DT
by Joonyoung Shim 12 Jan '15

12 Jan '15

Some exynos boards require special handling of SD4_nRESET_OUT line for eMMC memory to perform complete reboot e.g. Odroid X2/U3/XU3 boards. This will support eMMC reset using DT from reset_misc of samsung common board file and each board files can support eMMC reset on non DT case.

Hello, This patchset adds support for the Solomon Systech SSD2828 bridge chip, which is used to convert parallel LCD interface into MIPI DSI interface and drive MIPI LCD display in some tablets. In particular, this allows to have a working LCD display in my Allwinner A31s based MSI Primo81 tablet. The core of the SSD2828 support code is generic and should work with any SoC (as long as the hardware supports the standard u-boot GPIO API). It also does not have any hardcoded assumptions about the MSI Primo81 display and should be able to drive any MIPI LCD panel (as long as the number of data lanes and the bitrate per lane is provided in the config struct). The code tries to follow the standard power-up sequence described in the SSD2828 datasheet. However it has been tested only on my MSI Primo81 tablet so far. The sunxi specific part includes a small glue code in the sunxi display driver and the defconfig update for the MSI Primo81 tablet. This can be applied after http://lists.denx.de/pipermail/u-boot/2015-January/200753.html 'sunxi: video: Add lvds support' patchset to the 'next' branch in the u-boot-sunxi repository.
